Rex BSPT Threading Die Set, 2 1/2– 4 Inch, Made in Japan - 162460

Japanese BSPT Threading Die Set

The REX 162460 Threading Die Set is a premium, Japanese-manufactured 4-piece chaser kit engineered specifically for high-volume mechanical plumbing, industrial piping, and oil & gas pipeline installations. Forged under strict quality control from hardened, wear-resistant alloy steel, this robust set is meticulously optimized to cut clean, precise 11 TPI British Standard Pipe Taper (BSPT) threads on large pipes ranging from 2 1/2 to 4 inches. By integrating a specialized 20 mm slim die width profile, these advanced alloy dies provide a lighter, more efficient cutting operation that drastically accelerates threading speeds while significantly reducing the required power consumption of the machine compared to conventional full-width dies.

Designed to fit seamlessly into the REX 291045 profiling die head, this system is built to transfer torque evenly across the pipe surface. This prevents pipe wall distortion and ensures uniform thread creation, maximizing the service life of both the threading machine and the die blades themselves. Whether handling heavy-duty commercial installations or critical high-pressure gas pipelines, the REX 162460 delivers perfectly traced tapers and exact 55-degree thread angles, guaranteeing gas-tight and securely bound pipe joints for every professional project.

Key Features & Benefits:

• High-Speed Execution: Optimized internal cutting geometry allows operators to finish massive 4-inch pipe threads at significantly faster speeds than standard manual setups, boosting site productivity.

• Easy Tool-Free Installation: Features distinct precision alignment notches that click directly against the spring-loaded ball bearings inside the die head, enabling quick, effortless blade swaps without removing the head from the threading machine.

• Two-Step Blade Performance: The integrated bite profile allows the dies to cleanly strip away any external surface coating and slice uniform, deep pipe threads simultaneously in a single pass.

• High-Torque Alloy Steel Durability: Forged under strict Japanese quality control with heavy-duty structural alloy, providing exceptional resistance against chipping, friction, and teeth wear during continuous commercial operations.

• Efficient Chip Removal: Milled clearance channels are specifically designed to allow metal debris and shavings to flow out smoothly, preventing internal clogging, minimizing machine vibration, and leaving a polished, burr-free thread surface.

• Advanced Profiling System: Engineered exclusively for original REX profiling die heads, allowing the tool to trace a perfect taper linearly along the pipe, which naturally lowers mechanical stress and overall power consumption.

• 11 TPI High-Load Contact: Precision-machined to cut exactly 11 threads per inch, creating the optimal surface area contact required to secure gas-tight, high-pressure industrial pipe joints.

• 55° Thread Profile Accuracy: Strict Japanese manufacturing tolerances ensure a mathematically precise 55-degree thread angle, perfectly matching standard international BSPT specifications to prevent thread binding or leaking during assembly.

• Reduced Radial Friction: The innovative, narrow 20 mm die width minimizes physical surface friction against the pipe wall, significantly lowering the operational heat generated during dry or poorly lubricated threading cycles.

• Uniform Material Distribution: The structural alloy composition is evenly balanced across all four die pieces to prevent uneven mechanical wear, ensuring that all cutting teeth dull at the exact same rate over an extended operational lifespan.
